2.3 Prevention of vibrations of the jaw crusher supporting structure Another example of problems in operation of high performance machines is jaw crusher operating in one of Polish mines. During operation of crushing stations high dynamic forces are present. All that load is transferred to supporting structures and foundations.

Depending of the type of rock geometallurgy to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wearresistant platesurface.
A feed hopper which feeds jaw crusher has 50 Mg capacity and it has a 4545 cm grizzly screen on it. Materials finer than 45 cm pass through a screen. At entry of the jaw crusher, there exists a vibrating feeder equipped with steel chains for homogeneous feeding. A 80 of crusher final product is less than 89 mm. A rock
Figure 5.1 Schematic diagram of a crusher showingg the open and closedside settings. 5.1 Jaw and Gyratory Crushers. Jaw and gyratory crushers are used mostly for primary crushing. They are characterized by wide gape and narrow discharge and are designed to handle large quantities of material. The capacity of the crusher is determined by its size.
Jaw crusher units with extralong, articulated crusher jaws prevent coarse material from blocking while moving all mounting elements of the crusher jaw from the wear area. A more even material flow may be affected if the transfer from the prescreen or the feeder trough is designed so material simply tilts into the crushing jaw.
The laboratory crushing followed the method description from Norwegian Public Roads Administration 2016. The sample is crushed twice, using a laboratory jaw crusher with setting 11 mm. In the first crushing stage, 6390 mm rock particles are crushed individually.
A method of conical crushing to achieve the grinding of feed material includes narrowing the crusher setting beyond the specified minimum limit to enable the head to periodically exert high levels of compressive crushing force, interspersed with low pressure relief periods for mixing of the particles, the cycle of crushing periods corresponding with the gyrational cycle of the head.

The moving jaw swings toward the fixed jaw in the forward stroke, material is crushed, and discharge takes place during the backward or freeing stroke. The jaw crusher pictured below can be used to crush items from large objects such as demolition debris or broken concrete to smaller objects such as asphalt or river rock.
A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called a fixed jaw while the other jaw called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker. The volume or cavity between the two jaws is called the crushing chamber.
Although jaw crushers are extensively used for a variety of materials, their operational characteristics are not well understood. This lack of understanding makes selection of the proper machine difficult. Hersam 1923 proposed a method for calculating capacities using a Dodgetype jaw crusher.
Sandvik QJ241 mobile jaw crusher. Revelling in its most compact machine in the series, Finnish company Sandvik has launched the QJ241 mobile jaw crusher said to be ideal for smaller operations. Like the rest of the range, the model promises maximum productivity with low operating costs, and has been designed with the user in mind.
A gyratory crusher includes a solid cone set on a revolving shaft and placed within a hollow body, which has conical or vertical sloping sides. Material is crushed when the crushing surfaces approach each other and the crushed products fall through the discharging opening. Hammer crushers are used either as a onestep primary crusher or as a secondary crusher for products from a primary crusher.
